In Metal Gear Solid 3, if the player calls Sigint while wearing the GA-KO camo, Para-Medic will chastize them for not knowing what GA-KO is. She will then call Snake cute. Also when the player first wears the camo, they will hear the sound of the Kerotan frogs that are scattered across the map. In the Nintendo 3DS version, Metal Gear Solid: Snake Eater 3D, the GA-KO camo is replaced with the Fruit camo, which serves a similar purpose, only it hears the cry of Yoshis.
